After the Heroine wakes up, she discovers that it's August 4 and that she has no memories of the people she had known before. When she is at home, a young boy named Orion, who had already known her three days after August 1st, explains how she lost her memories and a way to help her to get them back. However, if she isn't able to get her memories back, she will soon lose her memories to talk, eat, sleep, and breathe.
